DELAY IN PROCESSING ORDER, NOW BILLED INCORRECTLY

We app**** to change from a prepaid line to a postpaid line. Telkom took ages to implement the change over, which could have been done telephonically. Instead a technician comes to the premises with instructions to install a new line. Upon explaining to him he re-iterated that the change over could have been done telephonically. Upon receiving our first account, we are charged a service fee R543.86. Upon enquiring about this amount, agents state that it was for line installation. How do we get charged such a high amount just for switching from one package to another despite having a line which was installed ages ago??? When lodging a dispute we are told to pay the full amount of the account as investigation takes 3 to 4 weeks. Telkom is quick to snap on extra charges to your account but take their time to undo their errors. A clear case of someone not doing their work!!!
